Thursday on Fox News Channel’s “The Kelly File,” former U.S. Attorney General Michael Mukasey reacted to a report that current U.S. Attorney General Loretta Lynch had met with former President Bill Clinton while his wife, presumptive Democratic presidential nominee Hillary Clinton, was under investigation for her use of a private email server while secretary of state. Mukasey called the meeting a mistake and dismissed the claim it was a chance encounter. “I think it was a mistake,” Mukasey said. “People make mistakes all the time. It was a mistake because you don’t take a meeting with the spouse of somebody who was the subject of an investigation by your department. It’s not that that’s a written rule any more than it’s a written rule that a surgeon washes his hands before he operates. There are some things that are so elementary that you don’t have to have a written rule to have them in effect.” “Megyn, the attorney general is protected by a security detail of FBI agents,” Mukasey said. “I assume she was traveling with staff since she was on government business. The president is protected by a detail of Secret Service agents. They don’t work for the same department.
